Abstract
Apparatuses, methods, and systems are disclosed for selecting a transport layer protocol for SIP messaging. One apparatus includes a processor and a transceiver that receives a SIP message from a remote unit, the SIP message comprising a first request to initiate a session for an IMS MMTEL. The processor determines that the SIP message is communicated using TCP as a transport layer protocol and forwards the first request to a network entity, wherein the first request is sent using UDP as the transport layer protocol.
